Macintosh

allright so i got my self a macbook pro 15 inch with the i5 and whatnot.
has upgraded ram and 1tb hdd and im super happy! :)
Thing is, i installed eve via steam and run it in lowest quality but it lags like crazy.
it also responds really late, its like a overall superlag in the game.

as i am new to the mac i do not know what to do and how to fix it, i have been reading through the forums for a bit now but i can not say that i have found a solution as of yet.

if any of you gents would be so kind as to help me out and find a solution that would make the game lag less i would be very much glad.

also i am running eve in window mode now with a little window which made it lag less but i wish to run it in the bigger window so it fills the screen out but when i do that the video it self just lags.

please help me
